Use the DM30 for 2-inch to 6-inch diameter residential floor drains, roof vents and light commercial jobs.  The DM30 features a double tube frame for added stability when on the job. The electrical wiring of this machine runs through the top of the frame so normal wear will not expose the wiring. This machine can run several different sized reels which makes this machine very versatile with the flexibility of the cable diameter and length.
